1 Claim.

This invention relates to a tool for applying springs to a window sashat opposite sides thereof between edge faces of the sash and confrontingfaces of tracks along opposite sides of a window frame in which the sashis mounted for vertical sliding movement.

When a sash is shifted in a window frame to a raised or loweredposition, it often happens that pressure applied to the sash to 'move itwill cause the sash to be tilted in the frame and side edge portion ofthe sash will become caught in the tracks and such binding engagementcreated that it will be difiicult and often impossible to move thesashwithout first restoring it to its initial position in the frame totrue it and then applying pressure at two points or at its center tomove the sash in the desired direction.

In order to overcome this objection springs are employed which areapplied to side edge faces of the sash and extend longitudinallythereof, the springs being in the form of resilient strips bowedlongitudinally with their ends in biting engagement with the sash andtheir intermediate portions bearing against the tracks. These springsserve to maintain the side edge faces of the sash in slightly spacedparallel relation to confronting faces of the tracks and the sash willbe prevented from tilting and binding in the frame during raising orlowering of the sash. Therefore, the sash may be easily shiftedvertically in the frame to raised or lowered position and if the sashcords should be broken, frictional grip of the springs with faces of thetracks will hold the sash and prevent it from dropping in the frame andmashing a persons hand or fingers.

In order to apply the springs to a window sash they must be thust intoplace between the tracks and side edge faces of the sash topredetermined positions in which they extend vertically with their endsin biting engagement with the sash. This has been found difficult toaccomplish without removing the sash from the frame and it is,therefore, one object of the invention to provide a tool by means ofwhich the springs may be easily thrust into place between the tracks andthe sash and left in place when the tool is withdrawn.

Another object of the invention is to so form the tool that, when it isthrust upwardly between a sash track and the confronting side edge faceof a sash, the spring, which is formed from a thin strip of resilientsheet metal, will be carried upwardly with it and then left in placewhen the tool is shifted downwardly out of place.

Anotherobject of the invention is to provide a tool of this characterconsisting of an elongated body or carrier in which is slidably mounteda sheet metal strip or shield adapted to be shifted longitudinally ofthe carrier so that it may be moved to an extended position in which aside face of the shield may be engaged by teeth at ends of a spring andthus prevent the teeth from digging into the edge face of the sash andpreventing the spring from being slid longitudinally to the desiredposition.

Another object of the invention is to so form n the tool that teeth atthe lower end of a spring may be engaged between the extended shield andthe upper extremity of the carrier and thus allow the carrier to haveabutting engagement with the lower end of the spring and move the springupwardly with it as the tool is thrust upwardly between the sash and thewindow frame.

Another object of the invention is to provide a spring applying toolwhich is simple in construction and capable of being formed entirely ofsheet metal and thus cheaply manufactured.

This invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a view illustrating the manner in which a spring is appliedwith the improved tool.

Fig. 2 is a front elevation of the tool with a spring applied thereto.

Fig. 3 is a fragmentary sectional view showing a spring in place betweena window sash and the sash track of a window frame after being ap pliedwith the improved tool.

Fig. 4 is a transverse sectional view on the line 44 of Fig. 1.

Fig. 5 is a perspective view of the spring.

Fig. '7 is a perspective view of the strip. or shield slidably carriedby the body.

This improved tool is used for applying springs to a window sash Ibetween side edge faces of the sash and confronting faces of the sashtracks 2 of a window frame 3 where they will hold the sash true andprevent the sash from tilting transversely of the tracks and sticking inthe frame.

It is to be understood that the springs will be applied at oppositesides of the sash and may be located at any point desired intermediatethe upper and lower ends of a sash. The springs 4 areof.duplicateconstruction' and each consists of a thin strip of resilientsheet metal which is curved longitudinally and has its ends serrated toform a suitable number of teeth 5. The teeth have their ends bent toform spurs 5'. The springs may be of any length and width desired andcurved or bowed for their. full length so that, when applied, theirteeth will have biting engagement with side edges faces of the sash andtheir intermediate portions bear against confronting faces of the sashtracks, as shown in Fig. 3. Therefore, the springs will be held firmlyin engagement with the sash and move therewith along the sash tracks infrictional engagement with it when a sash is opened or closed. The

' springs hold the sash spaced slightly, from the tracks and prevent thesash from being tilted in the frame during opening or closing movement.

V which the carrier is grasped during use of the tool. A shield 9, whichis also formed ofthin sheet metal and is preferably resilient, isslidably carried by the body or carrier 6 with its side edge portionsoverlapped by the flanges 1. A handle to formed of stiff metal, iscarried by the shield adjacent its lower end and has its shank H bent sothat when the shank is brazed or otherwise secured to the shield thehandle will project therefrom, as shown in Figs. 1 and 4, and may beeasily grasped when shifting the shield longitudinally of the carrier.

When the tool is in use to apply springs to a window, the shield 9 isshifted upwardly to extended position and a spring applied against aside face-of the shield, as shown in Fig. 2. It should be noted that thespring has a side edge portion projecting laterally from the extendedend portion of the shield and that the teeth at the lower end of thespring fit between the rear face of the shield and the upper end of thecarrier, one tooth being disposed outwardly from the 45 adjacent sideedge of the carrier. The carrier is then disposed against the surface ofthe track 2, under the raised sash I, with the spring also bearingagainst the surface of the track and the extreme upper end portion ofthe shield, which extends beyond the upper end of the spring, engagedbetween the track and the confronting side edge face of the sash. Thetool is then thrust upwardly between the sash and the track and, sincethe upper end of the carrier or body 6 has abutting engagement with thelower end of the spring, the spring will be carried upwardly with it.After the tool has been thrust upwardly as far as they operator deemsnecessary, the shield 9 is shifted downwardly by means of its handle iiito retracted position within the carrier and the resiliency of thespring will cause the spurs 5' of the teeth 5 to be forced into the woodof the sash and its intermediate portion to have close contactingengagement with the face of the track 2. The entire tool is thenwithdrawn and the spring will remain in place between the sash and theconfronting wall of the track. Since the springs will be under tension,their resiliency will hold the spurs of the teeth embedded in the sashand the springs will maintain the sash in spaced relation to inner wallsof the tracks so that said sash will slide easily and is prevented fromcanting and becoming caught in the frame.

Having thus described the invention, what is claimed is:

' within the body to extended position in which it projects from theupper end of the body.
